Kennedy’s sons at odds with his widow over institute

The already frayed relationship between Vicki Kennedy and her late husband’s children is at the breaking point, with the two sons growing increasingly convinced that she is jeopardizing the senator’s legacy and mishandling the creation of the $71 million institute that bears his name.

Much of the conflict centers around the construction and governance of the Edward M. Kennedy Institute for the US Senate, a project that faces potential cost overruns, according to a close family friend who was authorized by some family members to speak on their behalf, but who declined to be named.
